The present invention relates to heated massagin devices and, more esciall to those of t e type which are'electrically eat- Other objectswill appear in the course ofthe detailed description now to be givenwith reference to the accompanying drawings in which Fig. 1 is a sectionthrough one constructive embodiment of the inventlon; Fi 2 shows, insection, a slightly modified orm of the device represented in Fig. 1;Fig. 3 is an elevation of a second possible form of the invention.

Referring to Figs. 1 and 2 of the drawings, there is shown a massagingassembly consisting of a hollow shaft a. carrying a pair of handles b,ahelicoidal resistance c spirally Wound on shaft a,-a two-wire cable c1for supplying current to resistance 0,-an external massaging shell ehaving indentations, corrugations or the like formed thereon and freelyrotatable on shaft a,-a layer of heat insulating material f interposedbetween elements c and e, and formed of superposed layers of asbestosheld together by a binder, or of porcelain, plaster, rick or any othersubstance capable of storing the heat given ,oi by resistance c andslowly transmitting the heat so accumulated to shell e,- an insulatingsupporting shell for resistance c (ebonite, porcelain or metal coveredwith insulating material) ,-and asbestos rings adapted to heat insulateshell j from shaft a.

The essential novelty in the present invention lies in the structure ofthe combined wall e, In the prior art devices, the latter has been metalcorresponding to element e which conducts the heat so rapidly fromresistance c that either the subject being massaged is eX- posed to thedanger of being scorched or else the operator is subjected to theannoyance of having to repeatedly pull cable c1 from its formed of arelatively thin sheet of 313,575, and in Switzerland October 84, 1927.

socket during the massaging operation. By interposing a layer ofheatfstoring material between c and e, the temperature of e graduallyrises during the course of massaging and the subject being massaged isable to better support relatively high temperatures. Moreover the devicema be used continuously without having to pu cable c1 from its socket.

Itis to be understood of course, that, while elements e and f have beenshown separately-this being a preferred form of the invention-the may bereplaced by a single relatively thlk wall of metallic or otherappropriate material having a'large heat capacity. It will benoted,rhowever, that by' providing a thin external wall of metal (e andan internal layer of heat insulating material (f), a structure combininghi h heat capacity and ver light Weight is o tained. The structure s owninvFig. 2 difers from the one represented in Fig. l only in providingmeans for changing external wall e so as to vary the sha e vof theprotuberances formed thereon. 1ilere elements e and f are separated by alayer of Wire-gauze or perforated metal 71l adapted to maintainsubstance f in position when wall e isremoved. Wall eis supportedbetween a removable endelement f1 and a non-removable element f2. By,unscrewing threaded ring f3, and sliding end-element f1 off of shaft a,wall e may be removed and replaced by a similar element of desiredshape. Obviousl element fx may be made non-removable an f2 removable.

The structure represented in Fig. 3 is a single-ended heated massagingdevice intended to be used on special parts ofthe body.

The massage roll d is here rovided with k hemispherical extremities an'is supported on a rigid curved arm g carrying cable 01 and covered by aheat insulating material g1 .such as varnish or shellac for preventingaccidental scorching of the skin when arm g contacts therewith. Tofurther heat insulate arm g, a heat insulating segment g2 formed ofporcelain, mica, asbestos or the like may be interposed between themassage roll and arm g.

A massage instrument comprising a hollow shank, a sleeve of insulatingmaterial carried by said shank in fixed re ation thereto, an electricalheatin coil mounted on said sleeve, and a. rotatab e massage rollrotatably carried by said shank completely enclosing Said heating coilbut spaced therefrom, sai

massage roll having an external composite wall composed of an exteriorap licator shell and an inner layer of solid reiiactory heat storingmaterial lining said shell, said lining being exposed directly to theheat radiations of the coil and means passing through said shank forconducting current to sai coil.
